MECHANISM-SUPPORT FOR TALKING-MACHINES.

To all whom it may concern:

Be it known that I, Josnrn C. KENNEY, a citizen of the United States,residing at Scottdale, in the county of Westmoreland and State ofPennsylvania, have invented certain new and useful, Improvements inMechanism-Supports for Talking-Machines, of which the following is aspecification.

This invention relates to the subject of acoustics, and has particularreference to a novel mechanism support for talking machine cabinetswhereby the sounds produced are greatly clarified and, generallyimproved in tone.

To this end the invention contemplates a cabinet construction, whereinthe entire sound reproducing mechanism, including the motor and soundamplifying horn, is mountwhich rests upon a resonant plate and has noother connection or point of attachment with the surrounding cabinet orhousing. 1

A- further object of the invention is to provide a simple and racticalconstruction which is easily assemb ed and readily accesmaking repairsor adjustments to the motor or other operating parts.

With the above and other objects in view which will more readily appearas the description of the invention proceeds, the same consists in thenovel construction, combination and arrangement of parts hereinafter 1more fully described, illustrated andclaimed.

A preferred and practical embodiment of the invention is shown in theaccompanying drawings, wherein:

The figure is a vertical sectional view of a cabinet embodying thepresent improvements, portions of the cabinet being shown in elevation.

Although the present invention is sus ceptible of embodiment in variousstyles of talking machine cabinets there is shown in the drawing anupright cabinet structure U which houses the entire sound producingmechanism and operating the motor M.

suspended from the under side thereof.

This table is provided with the supporting members 6, and also carries.the sound am plifying horn 7 which connects with the tone arm.Therefore, it will be apparent that the entire sound reproducing unit isarranged upon the carrier which comprises the table 1 and supportingmembers 6, and as will be seen from the drawing the said table and allof its associated parts are absolutely separate and independent from thecasing G and have no connection at any point therewith.

Referring now more particularly to the novel and distinctive feature ofthe invention it will be observed that the entire carrier is seated upona resonant rest preferably a glass plate 8 the same being supported uponsuitable felt, rubber or equivalent cushion elements 9 carried by thevertical corner posts or strips 10 in each corner of the cabinet. By.reason of the fact that the entire sound reproducing mechanism is solelysupported on this plate 8 the sounds and tones reproduced by the playingmechanism are greatly. amplified and clarified. And, because of thespecial mount ing of the resonant plate on the corner strips 10, none ofthe vibrations of the casing parts are transformed into audible soundsthat might otherwise be carried into the reprothat the present inventionproposes to provide a simple and practical mechanism support Whichnotonly apparatus, but also amplifies and clarifies the sounds, so as tomake the rendition of selections more attractive than with the usualcabinet construction.
